This week was my 2nd visit to CodeMash in Sandusky OH, where I spoke on Building with the Microsoft Data Stack. We covered a lot of ground and had a great conversation about the various choices a developer faces regarding which technologies and formats make sense, including LINQ, Entity Framework, OData, Web API’s and more. We built a session explorer and then worked with EF 5 in Model first and in Code First modes with Database Migrations.
